# SPACE vs U

The clearest difference is review sentiment: SPACE at 100% against U's 15%. SPACE also leads on rating (5.0 vs 4.0). U's advantage is ratings volume (507 vs 1). On price, update cadence, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

SPACE holds the better App Store score, 5.0 against 4.0. That said, the two scores are not equally well evidenced: U has 507 ratings behind it against 1, so its average is the more settled of the two. Written reviews point the same way: 100% of SPACE's written reviews are positive against 15% of U's.

SPACE ships an update every 3 weeks, U fortnightly. The most recent releases landed on June 1, 2026 and September 22, 2026 respectively.
